WebOn the H–R diagram, the star therefore leaves the main-sequence band and moves upward (brighter) and to the right (cooler surface temperature). Over time, massive stars become red supergiants, and lower-mass stars like the Sun become red giants. WebStars in this area of the HR diagram are usually referred to as red giants. The evolutionary track for the star as it undergoes the transition to a red giant is shown below: Figure 6.1: The evolutionary track on an HR diagram for a Sun-like star as it leaves the Main Sequence, cools off and gets redder as it evolves to the red giant phase. chef ghs607

Both men were working with spectra of stars — that is, they were studying the light from stars by using spectrographs. Those instruments break down the light into its component wavelengths. fleet pride san antonio tx

The categorization of stars according to the Hertzsprung-Russell
